Hi,
it is likely only some switching issue.
The card is dirt cheap compared to what one payed 1 1/2 years back for
the P7131 Dual and only misses radio and the remote.
Emmanuel in your above link got DVB-T working after using analog TV
first with card=109 and for sure not tuner=67, but the default 54.
You tried this too just with card=109 ?
If no success, it seems he was using tuner_config=3.

We must get at a point where we have something reproducable.
The missing mux can also be caused by 7MHz bandwidth instead of 8.
